Performance comparison of OOC codes at various receivers for OCDMA system

In this paper, the performance of Optical Code Division Multiple Access (OCDMA) system is analyzed at different receivers by using Optical Orthogonal Codes (OOCs). Performance analysis is considered for the chip-level detector and optimum receiver. Our results demonstrate that optimum receiver require less BER i.e. 5.70e−008 than chip-level detector i.e. 2.54e−007 for fixed number of users i.e. for 100 users with code-weight as 9 and code-length as 2000.
